The RNLI has appointed Mark Dowie, a senior banking professional and one of its volunteers, as its new chief executive.
Dowie will succeed Paul Boissier, who has led the Poole-based charity since 2009, on 15 May.
Dowie has extensive experience as a trustee and volunteer, but this will be his first paid role in the voluntary sector.
He was most recently chief executive officer for corporate and institutional banking at Standard Chartered bank, a position he left in 2016.
He led the global wholesale banking business and was responsible for nearly 20,000 people in 62 countries.
Dowie is currently the lifeboat operations manager at Salcombe RNLI in Devon. He will relinquish the role when he takes up his new position.
A former Royal Navy supply officer, he is also a trustee of the Royal Navy and Royal Marines Charity, which supports sailors, marines and their families.
He has owned a marine services company and served as a magistrate in Devon. He is a keen sailor and a gyrocopter pilot.
In a statement, Dowie said he was "delighted and incredibly proud". He added: "I’ve seen first-hand the dedication and commitment of the RNLI’s volunteers and staff to help save lives and keep people safe."
Stuart Popham, chair of the RNLI, said Dowie would bring "a range of impressive attributes and experience" to the role.
"He has a wealth of corporate leadership experience and a real affinity for the sea," Popham said.
The RNLI is one of Britain's biggest charities. According to its latest annual report, for the financial year ending 31 December 2017, it has 2,440 staff and generated income of £202m, up from £191m four years earlier.
An RNLI spokesman declined to confirm how much Dowie would be paid but said he would be in the same pay band as Boissier.
The annual report for 2017 says the charity's highest-paid member of staff, who is not identified, earned between £160,000 and £169,999.
It says the charity’s chief executive received aggregate employee benefits including employers’ national insurance contributions of £188,871 over the course of the year.
